Description

The WSD-EML Emergency LED Driver is a self-testing battery backup driver that keeps LED fixtures lit during a power outage. It outputs 170V DC and connects to a fixture’s 0-10V dimming wires (DIM+/DIM-) when the fixture’s normal driver power exceeds the emergency driver’s rated output. Available in 8W, 15W, and 20W output tiers to match a range of fixture wattages, it is UL Listed and built for indoor dry and damp locations.

• UL Listed (cULus, file E530386)
• Input voltage: 100-347VAC, 50/60Hz (an unswitched AC power source is required); input current 0.1A max; input power 12W max
• Output voltage: 170V DC; output power varies by model — see Variations table
• Constant power emergency output with built-in self-test; double-click the test switch in emergency mode to end the current test stage
• Must connect to the fixture’s 0-10V dimming wires (DIM+/DIM-) whenever the LED luminaire’s power exceeds the emergency driver’s rated output; compatible with an optional 12VDC sensor
• Three wiring configurations depending on whether the LED fixture’s normal driver power is higher or lower than the emergency driver’s output power — see manufacturer’s wiring diagrams
• Designed for dry and damp locations only — do not use outdoors, and do not mount near gas or electric heaters
• Not for use in an air-handling fixture
• Ambient operating temperature: 5°C to 50°C (41°F to 122°F)
• 90-minute discharge time
• Case dimensions: 12.97″ x 1.97″ x 0.94″ (mounting center 13.1″)
• Test switch available as a wall test plate (with charging indicator) or a skinny remote test button — see notes below, since no inventory data was provided to confirm which accessory ships with this batch
• Customers are advised to recharge the driver for 24 hours every 6 months during storage
